質問：正しく関数にパラメータとして配列を渡す方法

、一つは空の配列に値を入力することができるようにすること？

は、なぜ私は、コール「calcGrossWages」

Answer 1

あなただけの配列の要素を渡すと、メインループを必要としないcalcGrossWagesの代わりに配列を渡す必要がありますcalcGrossWages

Answer 2

array[i]ある1つの配列要素ではなく、配列全体に該当する機能を言っていないエラーが出るん。配列の代わりにintとdoubleを渡そうとしています。関数は、すでに全体の配列を処理しますので、

/*Calculate the gross wages*/ 
calcGrossWages(hours, payRate, wages) 

あなたはループを必要としない、と機能：

は、配列の名前はhours、payRate、およびwagesなので、あなたはこのような関数を呼び出します何も返されません（結果はwagesに格納されます）。

（そして、サイドノートとして、これらの変数はグローバル、mainに対してローカルではないはずです。）
